INFLORESCENCE. 43 



umbel ; and the lesser umbels, which are borne by the rays of the 

 greater, are termed PARTIAL umbels. 



2. The very extensive natural order of plants called umbellife- 

 rous, have generally compound umbels. Ex. Carrot, Parsnip, 

 Parsley, Hemlock, &c. 



Radiate, (radiata) when the outer petals of the 

 external flowers are larger and longer than the rest. 



Floscular, (Jlosculosa) when the flowers are all 

 alike in size. 



8. CYME, (ct/ma.) PI. 11, fig. 4. A mode of flow- 

 ering, which has the general appearance of an umbel, 

 and agrees with it so far, that its common stalks all 

 proceed from one centre, but differs from it in having 

 the partial stalks variously subdivided. Ex* Elder, 

 Sambucus niger, and Snowball, Viburnum. 



9. PANICLE, (paniculaS) PI. 11, fig. 5. Bears the 

 flowers dispersed upon foot-stalks variously subdi- 

 vided. 



Observation. It is a sort of branching diffused spike composed 

 of a number of small spikes which are attached along a common 

 footstalk. Milne. 



Lax, (diffusd) when the stalks are distant. Ex. 

 London pride, Saxifraga umbrosa 9 and Common Oat. 



Divaricate, (divaricata.) Spreading ; when the par- 

 tial stalks form an obtuse angle with the common 

 peduncle. Ex. Brixa, and Red Top, Jlgrostis vul- 

 garis. 



Dense, (coarctata) when the foot-stalks approach. 

 Ex. Phleum paniculatum. 



One-sided, (secunda) leaning one way. Ex. Or- 

 chard grass, Dactylis glomerata. 



10. THYRSE, (thyrsus.} PL 11, fig. 6. A panicle 

 contracted into an ovate figure. Ex. Lilac, Syringa 

 vulgaris. 



Observation. 1. In the thyrsus the inferior peducles extend 

 horizontally, whilst the upper ones are nearly upright.
